Curious about how building performance standards are decided upon?
The IECC, or “model code”, establishes the minimum requirements for building energy efficiency by specifying the performance levels for the building envelope, mechanical systems, lighting systems, and service water heating systems in homes and commercial businesses. This model code is updated every three years, and within those three years there is a LOT of behind-the-scenes work going on to determine the changes for the next version. In this episode, we learn all about the long and lengthy code development process from SWA’s own Gayathri Vijayakumar.
